SIGNOBS TO VACUUM OIL COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEWYORK .RECEPTACLE FOR IETROLEUM AND THE LIKE Application illed October 8,1928. Serial No. 311,058.

invention is to provide a receptacle, for the purpose in question, withsimple and effective means for heating the contents of the receptacle topermit such contents to be withdrawn in liquid form under conditions of1 temperature in which the contents would readily.

The heating means in question have athe form of a tubular conduit orpipe fixed wlthotherwise be solid or too viscous to flow in thereceptacle and adapted for connection with an external source of a Huidheating medium, such as steam or hot water, and the invention'resides inthe particular form of such conduit and its relation to the dischargeorifice of the receptacle, whereby the desired Aor heads.

result is secured in the simplest manner and with the occupancy of aminimum space by the conduit. The invention com rises also convenientandY effective means or attaching the ends of the conduit to the. wallsof the rece tacle in such a way as to avoid leak.- age of t e contentsat such points of attachment. i

In the drawings:

Figs. 1 and'2 are, res ctively, V4a plan view and a side elevation o asheet-metal drum or barrel provided with heating means em bodying thepresent invention;

Fig. 3 is a sectional view on the line 3-3 in Fig 1 and on a largerscale; and

Figs. 4 and 5 are sectional detail views of the inlet and outlet endsrespectively of the heating conduit, together with the means by which`these ends are attached to the walls of the drum. l f

The invention is illustrated as applied to a sheet-metaldrum 1 ofordinary form, having. cylindrical side walls and fiat end 'walls Theupper head has the usuallarge filling opening, closed my a cap`2. Forthe withdrawal of the contents, the drum is provided, in its' side wall,adjacent'the lower ead, with an outlet opening or'spud closed by a plug.3. When the contents of the receptacle are fluid, they may .bewithdrawn through this outlet opening with the drum either standingupright, as in Fig. 3, or lying horizontally, with the outlet opening atthe bottom. l

The heating conduit in which the invention is particularly embodiedcomprises a pipe `,bent so as to have two limbs at a right angle witheach other. One end of this pipe is connected with `an opening in theupper end ot the drum, while the other end 1s connected with an openingin the side wall near the lower head, -as shown in Fig. 3. One of thelimbs of the pipe, therefore, extends vertically from the top nearly'tothe bottom of the receptacle, while the other limb extends horizontallyacross the bottom of the receptacle. Preferably, the heating conduit andthe outlet opening are arranged to lie in the same plane;

The form and arrangement of the heating conduit is such as to insuresuflicent heating and effective discharge of the contents of' the drum.It will be evident that in withdrawing i the contents it is desirable,at the outset and throughout the operation, to heat and melt thecontents at the bottom and adjacent the outlet opening. Thisl result isimmediately effected by the horizontal limb of the conduit extendingacross the bottom. It is necessary, further, that asv the contents atthe bottom are withdrawn, the superincumbent contents shall flow anddescend, and this result is secured by the vertical limb of theconduiteX- tending'from the bottom to the to of the receptacle.. It should benoted that, 1n either the upright or horizontal position of thereceptacle, there is a horizontal limb along the lowermost portion orbottom and avertical limb extending from the bottom to the uppermostportion or top, and that these limbs converge and communicate .at theinterior angle adjacent the outlet o ening.

' In order that the eating conduit vor pipe may be conveniently andsecurely attached to the walls of the drum, the construction shownparticularly in Figs.` 4 and 5 is used. 'As shown in Fi 4,thisconstruction includes a bushing 6 aving internal. and external threadedcylindrical surfaces, this bushing having an outwardly extending flangeat its outer end and an inwardly extendin ange at its inner end. A nut 9is screwe on the external threaded surface to clamp the bushing in placein an o ening in the head of the drum, and a gasket g, interposedbetween the head and the outer ilange of the bushing,

provides a Huid-tight seal at this joint. The upper end of the heaterpipe 4 extends into the bushing and is anged at its extremity, and agasket 8 is interposed between the pipe Harige and the inwardlyprojecting flange at and a sealing gasket 13 interposed between thebushing and the wall of the drum. In this case, however, a' gland nut 11is substituted for the plug 5 and arranged to compress n packing 12around the end of the heating pipe.

The invention claimed is: A

1. Ina receptacle for petroleum and the like, the combination, with agenerally cylindrical shell provided with an opening, for the dischargeof its contents, adjacent the angle between the side wall and an endwall of the shell, of a tubular conduit, for the passage of externallysupplied heating fluid, enclosed within the shell and bent toapproximately right-angleform, the limbs of said conduit beingsubstantially parallel, respectively, with `said end wall and side wall.

2. Ina receptacle for petroleum and the like, the combination, with ashell provided with two openings in the walls. thereof, of a tubularconduit, for the passage o f externally supplied heating fluid,extending, within said shell, from one of said openings to the other,

and means, for making a fluid-tight joint between each end of saidconduit and the'adjacent wall of the shell, comprising a bushing havinginternal and external threaded cylin' r11-ical surfaces, anoutwardly-extending flan e at its outer end and an inwardly-ex ten ingiiange at its inner end, a nut screwed on said external. threaded:surface and cooperating, `lwithy said v outwardly-extending flan e, tofix the bushinghinythe wall of the shel, an externally threaded andcentrally bored member screwed into'the bushing and engaging the end ofsaid conduit, andpacking surrounding the end of the conduit andlcompressed between saidf member and said inwardly extending flange onthe bushing.
